Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] Such as figure 1 As shown, the proportional electromagnet static characteristic test equipment, the operation of this equipment: firstly, the proportional electromagnet 5 is preheated for 15 minutes, in order to prevent the armature from leaving the 0 position, it is guaranteed by the follow-up characteristic of the servo motor 1. The ball screw 2 is driven by the servo motor 1 and keeps in contact with the armature all the time. The accuracy of each input of different duty cycle is guaranteed by the high precision of the servo motor's rotation angle. The axial displacement value of the ball screw 2 is collected by the displacement sensor 3 and input into the computer 7 . The electromagnetic force generated by the proportional electromagnet is input into the computer 7 by the force sensor 4 through the amplifier. Through computer processing, the force-displacement...

Description

technical field [0001] Proportional solenoid static characteristic testing equipment for proportional solenoid valves. Background technique [0002] Proportional solenoid valves, as electro-mechanical conversion components of electro-hydraulic proportional control components, are widely used in automatic control circuits in various fields, and their function is to convert electricity into force or displacement output. Due to its high control precision and strong anti-pollution ability, functions such as pilot control load and pressure compensation tend to replace servo valves. The proportional solenoid valve is controlled by PWM (Pulse Width Modulation, also known as duty ratio control technology), and the characteristics of the proportional solenoid of the driving part match the solenoid valve, which directly affects the performance of the solenoid valve. In the static characteristics of the proportional electromagnet, when the input current is constant, the external force...
